Selena Gomez Shows Butt, Teases ‘Secret Project’ In Sexy New Pic

Apparently Justin has really brought out the sexy side of Selena! The singer posted a new photo on Instagram in one of her most scandalous outfits ever — and was teasing something super secret!

Selena Gomez‘s pics just keep getting racier and racier. Four days after she posted a nearly-naked pic of herself behind a sheer curtain, she’s now posing in front of a mirror in a sheer-paneled top and boy shorts — and the pic is showing her from the back!

Selena Gomez’s Butt Exposed

“.. Secret project,” Selena captioned the pic. In the photo, Selena looks at herself in the mirror of a vanity and is pushing her hands through her hair. Since it’s taken from the back, we can see that the top has sheer-netting and the shorts are extremely short!

This looks like the latest in the Selena-Justin Bieber selfie showdown, since the two continue to post sexy pics of themselves! On the same day, Justin shared two pics of himself with an open button-down on revealing his full chest and his Calvin Klein underwear. He asked fans in the caption, “What if I do a Calvin Klein campaign ♛ ? Comment below yes or no.”

While they may be battling on Instagram, it’s even more steamy on their own private accounts!

Justin & Selena’s Sexting Continues

“He gets plenty from her and has a slew of pictures and videos of her that would make the Internet explode,” a source close to Justin told HollywoodLife.com exclusively. “He gets all the important stuff to him for himself.”

Well let’s hope so! Apparently with their busy schedules, the couple doesn’t get to spend as much together as they would like so they sext, have Skype sex, and send each other naked pics to stay intimate!

So, it looks like Justin won’t care how scandalous the pic is — since he gets way more. What do you think, HollywoodLifers? Do you think Selena’s secret project has something to do with Justin? Let us know!
